6 Two Source Automatic Transfer System ASCO two-source systems are designed for automatic switching of loads between the utility source and an alternate source of power. Upon the loss of the utility power source, the system provides an automatic start signal to the alternate source of power. Once the alternate source has reached proper voltage and frequency, the system transfers the critical load from the utility source to the alternate power source. When normal power is restored the controls will retransfer the load to the utility and signal shutdown of the alternate power source after allowing a cooldown period. ASCO two-source systems include an automatic transfer switch, plus any or all of the following options; automatic engine starting controls, overcurrent protection for both emergency and normal sources, instrument meters, status annunciation, and audible alarm. The systems are designed to NEMA switchboard construction and are labeled to UL 891 standards. These systems can be designed for top cable entrance, bottom cable entrance or bus duct connections. The system shown in figure 7 contains a 1200 ampere closed transition automatic transfer switch with a 1200 ampere utility circuit breaker, multi-purpose meter, reverse power relay, and an alarm horn. Fig. 7 Two source system with main circuit breaker, protective relaying and and automatic transfer switch rated 1200 amperes. Product Features Normal, emergency, and/or load circuit breakers. Protective relaying (as required). Normal Source MM 32 Optional instrument meters for normal, emergency, or load for local monitoring. LOAD ATS Designs are based on NEMA and UL 891 standards. Engine Optional engine start control logic and/or load control logic. Designs available up to 4000 amperes utilizing ASCO 940, 962, 434, 436 and ASCO's new 7000 series automatic transfer switches. MM = Multi-Purpose Meter 32 = Reverse Power Relay ATS = Automatic Transfer Switch Fig. 8 One line diagram of the two source automatic transfer system shown in figure 7. Page 6

7 Three Source Automatic Transfer System ASCO three-source systems are similar to ASCO twosource systems except that a second alternate power source is added to back up the first if that power source fails. Upon the loss of the utility power source, the system provides all necessary controls to start both alternate power sources. The critical loads are automatically transferred to the first alternate power source that achieves acceptable voltage and frequency. The second alternate power source is then automatically shutdown after a time delay and cooldown period. If the first alternate power source fails, the second alternative power source will be automatically re-started and the load will be transferred from the first alternative power source to the second alternative power source. When the normal power is restored, the controls automatically retransfer the load to the utility power source. Figure 9 shows a three source automatic transfer system with two 940 automatic transfer switches and three distribution circuit breakers for feeding critical loads. Fig. 9 Three source automatic transfer system. Product Features Control logic for selecting between the alternative power sources. Normal, emergency, and/or load circuit breakers. Protective relaying (as required). Optional instrument meters for normal, emergency, or load for local monitoring. Designs are based on NEMA and UL 891 standards. Load Circuit Breakers NORMAL SOURCE ATS1 ATS2 Engine 1 Engine 2 Optional engine start control logic and/or load control logic. Designs available up to 4000 amperes utilizing ASCO 940, 962, 434, 436 and ASCO's new 7000 series automatic transfer switches. ATS = Automatic Transfer Switch Fig. 10 One line diagram of the three source automatic transfer system shown in figure 9. Page 7

8 Three Source Priority System Fig. 11 Three source priority system. ASCO three-source priority systems are similar to the ASCO three-source systems except they protect two critical loads rather than one critical load. Upon the loss of the utility power source, the system provides all necessary controls to start both alternative power sources. The most critical load is transferred to the first alternate power source that achieves acceptable voltage and frequency. The second most critical load is then transferred to the second alternate power source when it achieves acceptable voltage and frequency. If the alternate power source feeding the most critical load should fail, the most critical load would be transferred to the second alternate power source and the second most critical load would be shed. When the utility power source is restored, the system controls automatically retransfer the loads to the utility and both alternate power sources are run for a cooldown period and then shutdown. Figure 11 shows a three source priority system containing a priority selector transfer switch (ATS-2) and seven distribution circuit breakers. ATS-1 and ATS-2 are wall mounted automatic transfer switches and are not shown in this line-up. Product Features Priority selector transfer switch. Control logic for selecting between alternate power sources Normal, emergency, and/or load circuit breakers. Protective relaying (as required). Optional instrument meters for normal, emergency, or load for local monitoring. Designs are based on NEMA and UL 891 standards. Optional engine start control logic and/or load control logic. Designs available up through 4000 amperes utilizing ASCO 940, 962, 434, 436 and ASCO's new 7000 series automatic transfer switches.

9 Soft Load Transfer System ASCO soft load closed transition transfer switches provide a make-beforebreak transfer of a building load from a utility power source to an alternate power source. This system automatically brings the engine generator into synchronism with the utility source, then gradually shifts the load from the utility to the engine generator with virtually no voltage or frequency fluctuations. Figure 13 shows a typical soft load transfer system containing an ASCO closed transition transfer switch. Product Features Open or closed transition transfer between normal and emergency. Emergency or peak shave mode of operation. Engine start control logic and load control logic. Available configurations include either an ASCO 434, 436 or ASCO s new 7000 Series closed transition transfer switches through 4000 amperes. The transfer system configuration can also accommodate power circuit breakers. Normal and emergency circuit breakers can be provided when using a transfer switch for overcurrent protection. Full manual paralleling operation (standard). Protective relaying (as required). Optional instrument meters for normal, emergency, or load for local monitoring. Designs are based on NEMA and UL 891 standards. Fig. 13 Soft load transfer system.

10 Custom Applications Selective Load System Selective load systems allow one load at a time to be operated when normal power fails. The system uses the minimum amount of auxiliary power for operation so the alternate power source can be sized for only one load at a time. The selective load system can be designed to handle any number of loads in any combination of sizes to suit the customers needs. The only interfacing between the ASCO selective load system and the load controls are power cables. The system can be used with any electrical load application where only one load out of a number of loads are to be operated from the alternate power source at one time. A typical application is with multiple banks of elevators when you want to enable only one elevator at a time to operate under emergency conditions. The system can be supplied with a separate control panel, which allows loads to be selected from a remote location. Fig. 15 Selective load system. Figure 15 shows a typical selective load system with transfer switches for five loads. The control panel has a selector switch and position indication of each load. Transfer Switch with Distribution System Transfer switches can be provided with normal and emergency circuit breakers for overcurrent protection, plus any combination of distribution circuit breakers, bolted pressure switches, or fusible disconnect switches. Figure 16 shows a switchboard containing a circuit breaker on the normal source of the automatic transfer switch plus a distribution panelboard of molded case circuit breakers to protect critical downstream loads. The cubicle on the left end of the system provides monitoring and control of the distribution system. Fig. 16 Transfer switch with distribution. Page 10

11 Custom Applications Transfer Switch with Bottom Bus Risers Figure 17 shows a 4000 ampere transfer switch with bus risers for bottom entry bus duct on both the normal source and load connections. The emergency side of the transfer switch has lugs for cable connections from the top of the enclosure. This demonstrates our capability to meet custom service entry requirements. Fig. 17 Transfer switch with bottom bus riser. Transfer Switch in an Outdoor Enclosure Figure 18 shows a transfer switch with a fuse disconnect switch on the normal side. The switch is in a non-walk-in NEMA 3R outdoor enclosure. The outdoor enclosure is designed for front and rear entry only with three point catches on the doors as well as provisions for padlocking. Outdoor enclosures are available for all ASCO transfer switch products. Fig. 18 Transfer switch in an outdoor enclosure. Page 11
